D.V. Cicchetti, A.S. Kaufman, and S.S. Sparrow (this issue) use six criteria to evaluate the published findings from seven different studies of PCB exposure and neuropsychological function. They point out a number of weaknesses or flaws in each study and conclude that these weaknesses make the overall conclusion that PCB exposure negatively…

The aim of the study was to examine factors that predict maternal stress, reported by mothers whose infants were diagnosed as having developmental disabilities at the beginning of participating in an early intervention programme "Me and My Mommy" and after one year. A second goal was to identify and to portray a subgroup of resilient…

Early interventionists are accountable for the progress of children receiving their services. Technically adequate measures of the progress of individual children are needed. While the Early Communication Indicator (ECI) for infants and toddlers is one such measure, data to support its use are limited to a single research report. In this…

Infant temperament is theorized to have a strong genetic basis. Yet, studies of the stability of temperament and molecular genetics research on temperament have revealed inconsistent findings. One reason may be because research has not taken into account the influence of early social experiences. We review research on aspects of infant…

The birth and hospitalization of a preterm infant have powerful effects on the emerging parent-infant relationship. Characteristics of parents, infant factors, and factors in the hospital and Neonatal Intensive Care Unit (NICU) environments--in addition to the circumstances surrounding preterm birth--may disrupt parent-infant relationships.…

Cognitive impairment has long been associated with the natural history of HIV among vertically infected children. In children, HIV may have a direct or indirect impact on the developing brain, may lead to global or highly specific consequences, and may be responsible for minor cognitive consequences or, conversely, long-term and severe disability.…

Newborn screening has existed as a state-based public health service since the early 1960s. Every state and most territorial jurisdictions have comprehensive newborn screening programs in place, but in the United States a national newborn screening policy does not exist. This results in different administrative infrastructures, screening…

In 2001, the authors assessed the quality of care provided to children in 51 care groups from 39 child-care centers in The Netherlands using the Infant/Toddler Environment Rating Scale (T. Harms, D. Cryer, & R. M. Clifford, 1990) and compared the results with the quality of child care assessed in 1995 (M. H. van IJzendoorn, L. W. C. Tavecchio,…

The objective of this review is to clarify the role of matching in family genetic studies of autism as a way of defining endophenotypes for linkage analysis. The concept of a confounding variable is reviewed and the importance of considering these in family studies of three endophenotypes in autism are considered: cognitive/language impairments,…

Infants parse speech into word-sized units according to biases that develop in the first year. One bias, present before the age of 7 months, is to cluster syllables that tend to co-occur. The present computational research demonstrates that this statistical clustering bias could lead to the extraction of speech sequences that are actual words,…

We investigated infant precursors of low language scores in early childhood. The sample included 373 probands in 130 monozygotic (MZ) and 109 same-sex dizygotic (DZ) twin pairs in which at least one member of the pair scored in the lowest 15th percentile of a control sample on a general language factor derived from tester-administered tests at…

Community-based parenting education programs have a unique role to play in the promotion of infant mental health. In contrast to classes that seek to accelerate child development, the author describes enrichment programs that promote parent-child bonding and healthy social and emotional development. The ParentSource program was developed on the…

Objective: The objective of these analyses was to explore maternal antenatal decisions about baby walker use, factors associated with these decisions and the relationship between antenatal plans to use a walker and postnatal walker use. Design: Cross sectional study. Setting: Mothers-to-be (n = 1174) participating in a cluster randomised…

The current review provides a summary and evaluation of the technical characteristics of five preschool screening batteries, including the Brigance Screens, DIAL-3, ESI-R, ESP, and FirstSTEP. These norm-referenced instruments were selected on the basis of their commercial availability, description as a screening instrument, and ability to assess…

While infant behaviour is influenced by maternal care, infant crying and dysregulated sleep can reciprocally affect maternal mood. The temperament and behaviour of two 4-12-months-old infant cohorts admitted with their mothers to a residential parenting program were examined using behaviour charts and the Short Infant Temperament Questionnaire…
